IMPROVEMENT IN FORCE-PUMPS.

Specification forming part of Letters Patent No. 179,293, dated J une27, 1876; application filed May 6, 1876.

To all whom it may concern:

Be it known that I, THEODORE GARDNER, of Horseheads, in the county ofGhemung and State of New York, have invented a new and valuableImprovement in Force-Pumps; and I do hereby declare that the. followingis a full, clear, and exact description of the construction andoperation of the same, reference beinghad to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a representation of a longitudinalacuteangle section, and Fig. 2 is a longitudinal vertical section, of myforce pun1p.',Fig.3 is a transverse vertical section; and Figs-4, 5, 6,7, 8, 9, 10, 11,12,155, and 14 are detail views of the same.

The nature of my invention consists in the construction and arrangementof a forcepunip, as will be hereinafter more fully set forth.

In the annexed drawing, A represents the bottom head-block, made concaveon its upper surface, and provided with a central opening, a, for theinsertion of the pipe that is to extend downward into the well. Abovethe head-block A is placed packing B, cut out so as to leave the concavesurface of the headblock open; and on this packing is the plate 0, whichhas one opening, b, in the center, and one opening, d, near one corner.On this plate is the packing D, provided with an opening correspondingwith the opening d, and has also a valve, a, over the opening I). E isthe head-block on which the cylinder rests. This head-block has threeopenings, 0 fh. e is directly over the opening d, and the two openings fand h form one on the bottom of the head-block, as shown. F is packingon top of head-block E. It has one opening corresponding with mainbarrel of cylinder, and two valves, b 11, over openings 0 and h in headblock E. The cylinder G has three bores or barrels, of which G is thelargest for the piston to work in. The other two, G and G are smaller,andthe three barrels coincide with the openings in head-block. On top ofcylinder is packing H. I is the second headblock from the top, havingthree openings, 1' k m. k m stand over barrels Gr G and a slot, 00, cutacross the head-block, connects is a concavity large enough to coveropenings k m, and admit of the Working of the valve 6. L is thepiston-rod, with piston M, composed of two metal plates with packingbetween them, and nuts above and below. The rodpasses throughstufiing-box N.

The piston can easily be repacked without taking the pump apart.

The operation is as follows: As the piston ascends, water is taken inthrough a, in headblock A, and fills the concave space thereof;

thence through I) in plate 0 at valve to, through f in head-block E, andfills barrel G of cylinder. As the piston descends, valve (1. closes,and the water is forced through h in head-block E at the valve d, up thebarrel G 1 through min head-block I, into concave space of head-block K,and out through a, the valve 01 then closing and holding it out. At thesame time water is being taken in at a in head-block A, through d inplate 0, c in headblock E at the valve 1), up the barrel G through theslot as in he head-block I, and fills the barrel G Now raise the pistonagain; the valve b closes, and the contents of the barrel G are forcedthrough 70 in headblock I into concave head-block K, and out throughopening n, the valve 6 closing and holding it out. At the same time thebarrel G is filled, as first described. .Valves 0 and 01 hold all thehydrostatic pressure out of the cylinder from the top, and the valves ab prevent all escape from the cylinder down the pipe. Thus, by workingthe piston vacuum is produced, and hydrostatic pressure forces waterthrough the vacuum produced to the cylinder.

An air-chamber may be used in connection with this pump, if desired.

What I claim as new, and desire to secure by Letters Patent is Thethree-barreled cylinder G, with the piston M, operating in the barrel Gin combina- In testimony that I claim the above I have hereuntosubscribed my name in the presence tion with the head-block E, withopenings 6 f of two witnesses. h, valves a b d, and head-blocks I K,provided with openings, passages, and valves, as described, allconstructed, arranged, and operating substantially as and for thepurpose set forth.
